Restore iphone 5s after family member death, no password..
Recently a family member has passed and we can't access his phone. I do not want to actually get into the phone, or retrieve the data, I would just like to restore to factory settings so that it can be reused by someone else. I connected it to itunes and I restored it, but now it needs the apple id still. I know his email associated with it, but I do not know the password. Also, it appears the email address has been deleted (Gmail). I just want to restore the phone so that it can be used, but right now it is completely unusable. How can I reset it so that the apple id is not associated with it?
